ICE-CREAM .nrsn-nn,

Application filed July 19, 1910; 1 serial No. 572,682,

To all whom it may concern: Be it known that I, EDWIN WALKER, a citizen of the United States, residing in Erie, county oi": Erie, and State of Pennsylvania, have invented a certain new and useiul Ice-Cream Disher, ofwhic'h the follow ing is a specification.

This invention is an ice cream disher embodying a novel construction of the retat-able scraper whereby it may be disconnected readily from the bowl or cup with out dismantling the finger operating mechanism, the :latter being provided for the purpose of imparting'rotary motion to--said scraper when the latter occupies an operative position within said cup or bowl.

Fo'rsanitary reasons, the scraper is removable irom the cup or bowl, but when the scraper is operatively fitted to, and rotated within, the bowl, it is necessary to provide means for retaining the scraper, in its operative position, said retaining means being unaffected by the rotation otthe scraper, whereby the scraper will not becr ine displaced when the device isin use.

Two leading features of the invention consist, first, of a hollow member, prefer ably a sleeve, rotatably fitted in the cup and adapted to support a scraper therein, and,

second, means coiperating with the scraper and the sleeve for retaining the scraper in operative engagement with said sleeve when the device is in use.

A salient feature of this invention, in a preferred embodiment thereof, consists of a sleeve and a nut connected operatively to each other for rotative movement, combined with a scraper having a stem which passes through the sleeve and is threaded into the nut, whereby the scraper is connected detachably to the nut and the sleeve.

In practical embodiments of the invention shown in the acctmpanying drawings, the

sleeve is connected to a cup or bowl indif ferent ways, whereby the connected sleeve and nut may remain attached to the cupo'r bowl when the scraper andits'stem are Withdrawn from said cup, but in a preferred form, the sleeve and nut are withdrawn from the cup, whereby the scraper and stem may be displaced in one direction through the larger open end of the cup, while the connected sleeve and nut may be withdrawn from the cup, by moving thesame 1n an'opposite direction to the direction of movement of the scraper during the act of :removingit. Furthermore, the gear by which thestem and scraper are rotated may be attachedfixedly to said stem for the purpose of removing the gear when the scraper is removed, but it is preferred *to' employ a sleeveof such length that said sleeve will findxa bearin'gat two points within the cup,

and to attach the gear to said sleeve, where'- by the gear, sleeve and nut are connected for simultaneous rotation. r I

According to, this invention, the sleeve carries or supports the nut'in such manner thatthe nut'will not have frictional ngagementwith a stationary part, such as the cup, whereby .the rotary motion of the nut with the stem, scraper, gear and sleeve will'not result 'in .thenut working loose upon the stem, norallowithe stem to become disconnected from the nutand the scraper to be detached from the implement during the use thereof, thus securinga most important advantage in a construction of disher of that type wherein the scraper stem is held in operative position by engagement with a member capable of rotation with the scraper; I

Other functions and advantages of my disher wil-lappear in the course of the detailed descripticn hereinafter given In the accompanying drawings I have illustrated difierent practical embodiments of the invention, but the constructions shown therein are to be understood as illustrative, only, and nct as defining the limits of the invention. V p i Figure 1 is a view in side elevation of an ice cream, disher embodying this invention. Fig. Q'isa plan view looking at the'clcsed end of the cupor bowl. 'Fig. 3 is a plan view of the bowl looking at; the open end thereof and showing a rotatable scraper. therein. F1g. t is an enlarged vertcal sec tion, partly in elevation,thrcugh the closed part of the cup'lllustrating one means for operating the scraper and reta ning said scraper detachably in prsition within the cup. Fig. 5 is a detail section on the line 5 5 of Fig. 4 illustrating means foriinr parting rotary motion to a gear whereby the scraper is rotated within the cup or bowl. Figs. 6, '7, and 8 are enlarged deta'ilsections somewhat similarto Fi l illustrating other embodiments of means whereby the scraper may be rotated within the bowl and retained in operative position therein while allowing for easy removal of the scraper for cleaning purposes. Fig. 9 illustrates a vertical section through a preferred form of bowl and a scraper co'o'perating therewith.

. In Figs. 1 andQ of the drawings there is shown an ice cream disher which in general respects is similar to those disclosed in certain prior applications heretofore filed by me, either as soleor joint inventor. On one end of aframe, A, is a bowl or cup, B, said frame having a suitable handle, a. The

frame is shown as havin an L1 standin lu b b b7 6, on which is pivoted a finger lever, C, said lever having a finger or thumb piece, 0, and an arm, 0. To this arm is connected a scraper operating'member, D, by means of pivotal pin, cl, said member, D, being shown as a rod having a series of. gear teeth, 0, forming a rack adapted to mesh with a gear, E, by which the scraper is rotated.

As shownmore clearly in Figs. 4, 6, 7 and 8 of'the drawings, cup, B, is closed at one end, as at b, the other end of the cup being open. 'In the closed end, I), of the cup is a chamber, F, the axis of which is in line with the longitudinal axis of the cup. Chamber, F, is partially closed at one end by means of a flange, f, the other end of said chamber being open and provided with a shoulder f.

In the construction shown in Figs. 4, 6, and 7 of the drawings I employ a sleeve, G, which extends practically through chamber, F. Said sleeve, G, is provided with an opening, g, angular or polygonal in cross section.

opening which is provided in flange, f, of the cup, and at its inner end said sleeve has a shoulder, g, which is upset so as to engage with the flange, 7, whereby sleeve, G, is retained within the closed part of the cup by the cooperation of flanges, f, 9. At the same time sleeve, G, is free to rotate in thecup for the purpose of imparting motion to the scraper, as will presently appear.

' Fitted loosely around sleeve, G, is a plate or washer, H, which is seated in the recess, 7, of the cup, whereby the plate or washer closes the outer end of chamber, F, and forms one of the two journals for sleeve, G. The disk or washer, H, is fitted loosely and externally on thesleeve before thelatter is introduced into the closed end of the cup, and after such introduction, the end of the sleeve is upset or flanged, as at g, for the purpose of retaining the sleeve within the cup while permitting it to rotate therein. It

1 will be noted that the inner end of thesleeve is journaled on the flange, f, of the cup, whereas the outer part of the sleeve is journaled in a bearing formed by the plateor In the construction represented in Fig. 4 sleeve, G, passes through a central washer, H, whereby the sleeve is supported by a plurality of journals in the closed part of thecup.

Gear, la, is secured rigidlv to sleeve, G, between flange, g, and washer, H. Said gear is positioned within chamber, F, of the cup, whereby it is concealed from view and protected from the accession of dust and from the material which is dished out by the operation of the implement. Thegear is made fast with the sleeve in any desired way for the purpose of rotating therewith. That part of the sleeve to which the gear is ap plied may be polygonal or square in cross section, and the gear may have a square opening whereby the gear is adapted to rotate with the sleeve.

In addition to chamber, F, the closed end of the cup is provided with a passage or opening, 6, the axis of which is at right angles to the axis of chamber, F, said passage or opening, 6, extending through opposite faces the cup and intersecting with the chamber, see Fig. 5. Rack, 6, of the operating chamber, D, is fitted loosely in the passage, e, for reciprocating movement therein, whereby the teeth, 6, of said rack are adapted to mesh with the teeth of gear, E, for the purpose of rotating the gear when member, D, is operated by applying pres sure to the finger or thumb piece, 0, of lever, C, in a manner well understood by those skilled in the art.

I designates a scraper, cleaner or similar element positioned within the bowl for the purpose of removing from the interior surfaces of saio bowl the material which is dished out by the operation of the implement. The scraper, or equivalent member, is shaped to conform substantially to the inside contour of the bowl or cup, and said scraper is shown as having a cross piece, z', the latter fitting snugly to the inner closed end of the cup.

J designates a stem, one end of which is fastened rigidlv in any suitable way to cross piece, 2', of the scraper, the other end of said stem being reduced and screw threaded so as to form a tenon, 7'. Intermediate the threaded tenon and the cross piece, 2', the scraper stem, J, is angular or polygonal in cross section so that the stem conforms to the passage, g, of the sleeve, whereby the stem may he slipped into the sleeve and coupled thereto for rotation with said sleeve when the latter is actuated by the rack and gear mechanism heretofore described. It is evident that the scraper may be introduced into the cup through the open end thereof, and that said scraper maybe withdrawn from the cup through said opening. During the insertion or removal of the scraper, stem, J, remains attached thereto, and when said scraper isinserted or withdrawn the stem moves lengthwise with respect to sleeve, G.

An important feature of the invention consists of means for retaining the scraper in operative engagement with the sleeve when the, parts are assembled for service, and in the embodiment of theinvention representedin Fig. a, the scraper is retained in position by a member herein shown as a nut, K. The nut is provided with flanges, 70, which are swiveled on sleeve, G, for the purpose-of retaining the nut in operative position on the sleeve, and of permitting the nut to have rotative movement upon said sleeve while the sleeve remains in a stationary posi% tion. The nut is shown as having a central internally threaded aperture, is, adapted for the reception of the threaded tenon, j, on stem, J, whereby the nut may be screwed upon the threaded part of the stem. As shown, the flanges, 71:, of the nut are turned below the shoulder, 9 produced on the outer end portion of the sleeve, G, said shouldered part of the sleeve extending be;

yond washer or plate, H.

From the foregoing description it is apparent that scraper, I, may be removed by rotating nut,K, on sleeve, G, in a direction to unscrew the nut from threaded tenon, j, whereby the stem and the scraper will be moved endwise until the nut is disconnected from the stem, afteriwhich the scraper may be lifted out of the cup, or the cup may be inverted so as to drop the scraper and the stem connected thereto out of the cup. The parts are thus disconnected for the purpose of exposing their surfaces whereby the cup and the scraper may be thoroughlycleaned and sterilized. To reassemble the parts it is only necessary to place the scraperwithin the cup in a manner for the stem to pass through the sleeve and its tenon, y', to enter the threaded aperture of the nut, at which time the nut is rotated in a direction to screw the tenon into said nut, whereupon the scraper will be drawn into, position within the cup until the cross member, 5, of the scraper engages with the inner flanged end,

g, of the sleeve; The scraper is thus connected operatively with the sleeve and the nut,

:T he implement be used in the well known manner for the purpose of filling the cup with cream, water ice, or any other substance, and when it is desired to discharge the molded cream, the cup' is inverted and lever, C, is operated, whereby movement is imparted to member, D, and gear, E, is rotated for the purpose of rotating the scraper within the cup, thus releasing the cream or other material from said cup, and permitting said material to be readily discharged.

It is desired to call attention to the fact that the nut rotates with the sleeve and the stem, J, when the member, D, imparts r0 work loose, onthe stem and permit the scraper to become disconnected from the cup. In-the embodiment shown in Fig. i, I have shown the gear E as formed integral with the stem g, although, manifestly, it may, if desired, be fixedly secured thereto or detachably secured against rotation thereon. The construction shown in Fig. 6 is the preferred embodiment of the invention for thereason'that the sleeve and the nut con nected thereto are removable from the cup independently of the scraper, i. 6., the sleeve and nut maybe withdrawn in one dimotion and the scraper with the stem attached thereto withdrawn in an opposite direction. The sleeve, G,is provided with the square or polygonal passage adapted to receive a square or polygonal stem, J, of scraper, I. The inner end of sleeve, G, is not flanged or shouldered, but it is fitted rotatably in bearingformed by flange, f, the outer part of the sleeve having a journal formed by plate or washer, 1-1, which is fitted removably in the shoulder, f, of the cup. Gear, E,fis attached externally to sleeve, G, at a point intermediate its ends, said gear being adapted to vlie within chamber, F, and to engagewith rack, e, on operating member, D, as heretofore described.

Nut, K, is slipped on or swiveled to the outer part of sleeve, G, so as to remain con nected therewith and to be supported thereby. The construction and operation of the device shown in Fig; 6is quite similar to that heretofore described in connection with Fig. 4, except than when the nut is unscrewed from the threaded tenon of stem, J,said stem and the scraper'may be withdrawn from the cup by moving the parts in one direction while the sleeve, the nut attached thereto, the gearfixed thereon, and the plate or washer, H, mav be withdrawn from the chamber, F, of said cun by moving the slee e in an opposite direction to that in which the scraper is withdrawn. The sleeve and the gear may thus be detached and exposed for cleaning and sterilizing them in the same mannerthat scraper, I, and stem, J, may be cleaned and sterilizedl Tn reassembling the parts for use, the sleeve is adjusted to the closed part of the cup for the inner end of the sleeve to find a bearing in flange, 7, while plate; or disk, H, is seatedin the shouldered part, f.

by member, D.

The construction illustrated in Fig. 7 di it fers somewhat from the construction of F igs.

4: and 6. Chamber, F, of the cup is not provided at its inner end with a shoulder, such as f, but at the outer end of the chamber the cup is formed with an inwardly extending flange, f Scraper, I is provided with a square or polygonal stem, J and with a washer, 7' the latter fitting snugly to the wall of chamber, F, so as to form .L bearing for the inner end of sleeve, G Gear, E is fixed externally on sleeve, G for the purpose of rotating the sleeve and the scraper when member, D, is operated. The sleeve is provided with a shoulder, g", and a groove, I The shoulder is adapted for cooperation. with flange, F, at the outer end of chamber, F. Nut, K is provided with a flange, which is turned into the groove, 9 of the sleeve, whereby the nut is rotatably connected to the outer grooved and shouldered end of the'sleeve. According to this embodiment of the invention, the gear E may be either formed integral with the sleeve G may be fixedly secured thereon, or removably secured thereto against rotation, but I have shown, in said figure, the gear as fixedly secured to the sleeve. According to this construction,the scraper may be'removed at will by simply manipulating the nut K while the sleeve and gear are maintained, at all times, within the cup. However, if the gear were detachably secured against rotation, the unscrewing of the nut K would allow of the withdrawal of the scraper from the cup as well as the withdrawal of the sleeve G from the gear, thereby allowing the gear to be dropped out of the cup.

In Fig. 8 of the drawings scraper, I is provided with a flange, 7' similar to the flange, j of Fig. 7. In this construction, however, I employa comparatively short sleeve, G the inner part of which does not extend across chamber, F, of the cup. Sleeve, G is provided with an annular groove, 9 adapted to receive a flange, 7, of the cup, whereby the sleeve is rotatably connected to the outer part of said cup. In addition to groove, 9 the sleeve is provided with an annular groove, 9 with which engages the inturned edge, 7c*, of nut K It will be noted that the sleeve is rotatably connected to the cup, and that the nut is stem.

rotatably connected to; the sleeve. Said sleeve, G is provided with a square or polygonal opening to receive a squareor polygonal part of stem, J the latter being rigidly secured in a suitable way to scraper, I In this form of the invention gear, 1 1, is not attached to sleeve, G but on the con trary, said gear is fastened rigidly in any suitable way to stem, J at a point between washer, j, and the polygonal part of the When the scraper, I is withdrawn by unscrewing nut, K from the stem, said stem, J and gear, E remain attached to the scraper and are withdrawn therewith from the cup. 'After cleaning the scraper, the gear and the stem, the parts may be replaced by inserting the stem into the sleeve, and rotating. the nut so as to draw the gear against the end of the sleeve. The washer, j, of the scraper forms a journal for supporting said scraper within chamber, F of the cup, the stem, J being secured in sleeve, G which is journaled in the outer part of the cup, thus insuring free rotation of all the parts when member, D, is operated to rotate the scraper by acting directly upon gear, E i

Fig. 90f the drawings illustrates a form of cup which I employ under certain conditions, such as when dishing ice cream to be deposited in edible cones, as now practised in the art. As shown, the cup, B consists of a substantially conical portion, 6 and a substantially cylindrical portion, 6. The cylindrical part, Z), is at the open end of the cup, and said cylindrical part forms an extension or continuation of the walls constituting the conical part, of said cup. The scraper, I is provided with members or blades, 2' whichconform to the interior contour of the conical and cylindrical parts of the cup sothat the scraper will operate eifectively upon the material adhering to the walls of the cup for the purpose of releasing said material and permitting the same to be readily discharged. \Vith scraper, I is associated a stem adapted to be supported and operated by either of the devices hereinbefore described. whereby the scraper is rotatably connected to the operating mechanism, and it may be disconnected by unscrewing the nut from the stem in an obvious manher. The employmentot a cup, such as B molds ice cream or other edible product so as to produce a cylindrical base portion and a conical body portion, which cylindrical base portion is adapted to enter the enlarged open end of an ice cream cone, thus exposing the conical part of the cream for ready access in eating it.
